| DefaultRasterMapProducer | | abstract public class DefaultRasterMapProducer extends AbstractRasterMapProducer implements RasterMapProducer(Code) | | Abstract base class for GetMapProducers that relies in LiteRenderer for
creating the raster map and then outputs it in the format they specializes
in.
This class does the job of producing a BufferedImage using geotools
LiteRenderer, so it should be enough for a subclass to implement
Generates a map using the geotools jai rendering classes. Uses the Lite
renderer, loading the data on the fly, which is quite nice. Thanks Andrea and
Gabriel. The word is that we should eventually switch over to
StyledMapRenderer and do some fancy stuff with caching layers, but I think we
are a ways off with its maturity to try that yet. So Lite treats us quite
well, as it is stateless and therefore loads up nice and fast.
